STORAGE-BATTERY GRID.

To all IIIHH)! it may com-t I'll.

Be it known that l. .losi-iiii .\l.\itx. citizen of the l'nited States. residing at. Bull'alo. in the county of Erie and State of New York. have invented certain new and useful .llli proveineuts in Storage .ltattery tlrids, of which the following a. specilication.

This invention contemplates certain new and useful improven-ients in plates or electrodes [or storage batteries. of that type in wltich the active element or material such as oxid of lead is packed into a. grid or grated framework, and the object of my invention is a grid orplate of this character which'will possess to a ltigh degree the characteristics of durability. highconth nivity and ellicieucy of service.

To this end. the invention consists iii certain constructions and arrangements of the parts of the grid. as will be hereinafter fully described and claimed. rel'erence being had to the accompanying drawing. in which:

' Figure l is a lace view of one embodiment of my invention: Fig. l-is a sectional view on the line -B of Fig. 1: Fig. I; is a sitnilar view on the liiie -l) of Fig. 1: Fig. 4 is a side elevation upon an enlarged scale of a fragment of the grid.

Corresponding and like parts are referred.

to in the following description and indicated in all the views of the drawings by the satne reference characters.

Referring to the drawing, the numeral 1 designates the frame of my improved grid, which may be of any desired size and which may be. if desired. provided with one or more bars .2 to strengthen it. .It niav be t'tililptisttl. for example. of antitnonious lead.

and is designed to have packed into it the active element or material. such as oxid ot lead. The trame is provided with suspending ltigs 3 and 4 of any desired shape atid const ruction. For the purpose of securing a high degree of conductivity and a maximum area of conductive points. as well as to secure durability and longevity in iise. the traniework. is formed with a series ol shelves Specification of Letters Patent.

or bars 5 which are shown in the present iiista-nce as extending parallel to each other and horizontal with respect to the frame. as well as being spaced from each other in superposed series. The frame 1 is also formed with two sets of obliquely extending ribs 6, which are arranged on opposite sides of the series of bars 5 and which are V-shape in cross section. as shown. These bars produce gratings or diamond shaped openings. leading into the chambers formed between the bars 5. From the foregoing description n connectioii with the accompanying drawings, itv will be seen that when the active material is packed lightly into a frame constructed in accordance with my invention. the said material will be securely held in place and that a maximum area of conductive points willbe l leret ofore all plates of the Faur'e type have been so constructed that they lose their conductive points through their discharge. owing to the shrinkage of the active By my invention, l overcoi'ne this defect. because the active material through discharge will shrink to the liars 5 and so increase the conductivity.

Having thus described the invention. what is claimed as new is:

l. A grid of the character described. consis'ting of a framework provided with a series of superposed and horizontally extending bars. and obliquely extending gratings on both sides of said bars.

2. A, grid of the character described. consisting of a frame provided with a series ol' spaced parallel and horizontally extending bars and two sets of obliquely extending ribs on opposite sides of said bars, the said ribs of each set intersecting each other. and the said ribs being V-sliaped in cross section.

in testimony whereof I allix my signature itt presence of two witnesses.
